Document Type and Number:
WIPO Patent Application WO/2022/138804
Kind Code:
A1
Abstract:
[Problem] To provide a novel solid electrolyte having excellent lithium ion-conductivity. [Solution] A lithium ion-conductive solid electrolyte according to the present invention includes a chalcogenide having a monoclinic crystal structure, wherein the monoclinic crystal has an a-axis length of 9.690-9.711 Å, a b-axis length of 11.520-11.531 Å, and a c-axis length of 10.680-10.695 Å, and has an axis angle β in the range of 90.01-90.08°. An all-solid-state battery according to the present invention comprises: a positive electrode having a positive electrode active material; a negative electrode having a negative electrode active material; and a solid electrolyte layer disposed between the positive electrode and the negative electrode, wherein the solid electrolyte layer includes the lithium ion-conductive solid electrolyte.
